You can run a pellet stove on a 300 watt genny.
I have both a pellet and wood stove. I'll burn maybe 45-50 bags of pellets and about 3 cords of wood. Neither are going full time, more like when I get home from work at 4pm and all weekend. I'll still spend a 1000 bucks in electricity during winter.
in Nova Scotia wood is 250 for a hardwood chord, pellets are 5 bucks+15% sales tax, and electricity is over 13 cents per KWH.
Don't sweat the petty things; Pet the sweaty things !!!
